The syphonject draws a concentrated solution from a bucket through a flexible suction tube . The solution is then diluted as it enters the water stream at an approximate ratio of 20 parts water to 1 part concentrated solution .

Requirements are: A full flow nozzle of 3-5 gpm. Minimum water pressure is 35 psi, max hose length of 50′. Any restrictions in the line downstream will cause backpressure and it will not work .
